Very short lived. He's tried to advertise them playing games together on stream, but with all the wisdom he accumulated over years of streaming, decided the best games for two people to play together were single player games. And wanting to one up his own stupidity, decided that the Yakuza 8 minigame island was the best choice for a debut two person stream. It basically amounted to Khet grinding out Phil's in game chores. Shockingly, this snore fest wasn't drawing in new viewers/huge tips and Phil claimed Khet was bored and she hasn't appeared since, but he was briefly teasing that they were considering other games. Oh, but anyone suggesting actual multiplayer games for them to play was a moron. I think he only teased it for a few weeks before forgetting about it entirely.
Probably the funniest thing about it was, despite not really having an actual game to play, Khet was displaying considerably more skill than Phil and was getting praised in the chat for her gameplay, which Phil was clearly jealous about.
